Design of Guidance Strategies Toward Better Driving Behavior in Typical Freeway Work Zones
With the gradual increase in the demand for daily maintenance, repair, and expansion, work zones have become critical nodes influencing traffic flow characteristics in freeways. Timely guidance of … [Read more...] about Design of Guidance Strategies Toward Better Driving Behavior in Typical Freeway Work Zones
An Evaluation of the Effectiveness of Digital Speed Limit Signs and Work Zone Presence Lighting on Speed Compliance During Lane Closure Operations
The NCDOT Work Zone Traffic Control Section is collecting speed data on 6 random Interstate/Freeway projects across the state that are using both Digital Speed Limit Signs and Work Zone Presence … [Read more...] about An Evaluation of the Effectiveness of Digital Speed Limit Signs and Work Zone Presence Lighting on Speed Compliance During Lane Closure Operations
Strategies for Improved Driver Behavior Within Work Zones
Work zones (WZs) are among the most hazardous roadway environments due to restricted geometry, temporary traffic control, and increased driver workload, which often lead to speeding and elevated crash … [Read more...] about Strategies for Improved Driver Behavior Within Work Zones
Driver Comprehension of Driveway Assistance Devices for Work Zones: Evidence from a Nationwide Survey
Driveway assistance devices (DADs) provide traffic control at low-volume access points on one-lane, two-way work zones without the need for flaggers. Interim approval for the optional use of DAD at … [Read more...] about Driver Comprehension of Driveway Assistance Devices for Work Zones: Evidence from a Nationwide Survey
The Effect of Advance Warning Systems on Headway Distributions in High-Speed Work Zones
In work zone traffic management, warning systems provide road users with real-time traffic conditions through messages or signals. This process aims to adjust driver speeds and headway distribution to … [Read more...] about The Effect of Advance Warning Systems on Headway Distributions in High-Speed Work Zones
